Title: Improvements in multiple objective photographic cameras
IPC: G03B35/10
Filed: 1939-01-27
Abstract: 524,335. Shutters for multiple lens cameras. FRANKE, P., and HEIDECKE, R. Jan. 27, 1939, No. 2880. Convention date, Feb. 9, 1938. [Classes 98 (i) and 98 (ii)] A photographic camera with more than one objective is provided with a separate shutter for each objective, a release mechanism common to the shutter, and an adjustable delay mechanism between the release mechanism, and one of the shutters allowing it to be operated with a predetermined delay, or simultaneously with the other shutter, or to be put out of action. In the form shown, the setting arm 8 of a diaphragm shutter is operated simultaneously with the setting arm 7 of a shutter 5 through a rod 9 with a pin-and-slot lost-motion connection 11, 12. A pin 13 on the setting-arm 8 is engaged by an arm 15 extending from a pivoted spring- urged toothed quadrant 16 which meshes with a pinion 80 connected by a gear train with an escapement 17 forming a delay-action device. In the set position, Fig. 3, the pin 13 enters a bend 23 in the arm 15, the spring 81 urging the arm downwardly. On operation of the release 30 of the shutter 5 the coupling rod 9 returns to the position shown in Fig. 3, but the operation of the shutter 6 is delayed owing to the pin 13 having to lift the arm 15 against the action of the escapement in moving out of the bend 23. The interval between the two exposures is adjusted by a disc 22 in which is a curved slot 21 engaged by a pin 20 on the quadrant 16, so that rotation of the disc determines the initial position of the arm 15 from which the pin 13 must raise it before escaping from the bend 23. For simultaneous release of the two shutters the disc 22 is adjusted so that the pin and slot 20, 21 raise the arm 15 clear of the pin 13. For independent manual release of the two shutters, the disc 22 is turned so that the tail 26 of a lever 24, which normally bears on the edge of the disc, enters a recess 27, allowing the hooked end 25 to latch the pin 13 until the lever is operated by a release stud 29.

Abstract: 705,510. Pulse storing and gating circuits. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Jan. 31, 1952 [Feb. 9, 1951], No. 3262/51. Class 40 (6) In a cathode ray tube store in which a charge pattern is set up on an insulating screen by the release of secondary electrons from areas of the screen and in which the charge may or may not be subsequently neutralized by electrons released from an adjacent area, the beam is moved either from a first area A to a second adjacent area B or alternatively from the first to the second and then back to the first. By arranging that in the first alternative the beam is moved to a third adjacent area C, the beam being switched on for equal times in both cases, there is no D.C. component in the output from the pick-up plate feeding the regenerative circuit. This allows more effective use of automatic control of the cathode current of the C.R.T. Circuit.-A master generator 10, Fig. 1, feeds X- and Y-scan generators 11, 12 and a brightup generator producing waveform, Fig. 2(a). Upon the occurrence of an output pulse, the waveform, Fig. 2(b), from strobe generator 17 permits the pulse, Fig. 2(c) from dash generator 16 to be effective so that a prolonged pulse, Fig. 2(d), passes to the grid of valve V3 to permit a pulse, Fig. 2(f), to pass to the anode follower 25 to deflect the beam in that direction. The read-write gating circut 20, 21 is similar to that described in Specification 705,474. If an "0 # or charged area is to be established, valve V1 is cut off at the suppressor so that from t1 to t2 the beam rests on area A and is then switched off. At time t3 the beam is switched on but also deflected by waveform, Fig. 2(e), from generator 13 to area B, so that the charge in A'is partly neutralized. At time t4 the beam is returned to area A and re-establishes the charged condition before being switched off at t5. If a " 1 " or uncharged area is to be established, the dash waveform, Fig. 2(c), is applied to terminal 27 to feed a pulse (f) to the output so that at time t4 the beam is further deflected to area C. The time constants RC of the cathode circuit of the C.R.T. is made long compared with digit period and by :- Alternative storage circuits, Fig. 3.-In order to ensure that regeneration continues in a series of stores 30, 31 the output of a store may be fed through diodes 33, 35, or 33', 35' the switch being rendered operative by battery supplied over diode 34 to isolate the store concerned.

Abstract: 798,372. Variable pitch propellers. GENERAL MOTORS CORPORATION. Jan. 30, 1957 [March 14, 1956], No. 3264/57. Class 114. A combined mechanical pitch lock and low pitch stop assembly for a variable pitch propeller comprises a device having a definite angular position for each blade pitch position, a stop engageable with the device at a predetermined angle to prevent rotation thereof and of the blades in a decreasing pitch direction, and a look engageable with the device to prevent rotation thereof and of the blades in a decrease pitch direction. A master gear 20 engaging toothed sectors 19 on the propeller blades to co-ordinate their pitch-changing movements is splined to a sleeve 25 itself splined at its outer end to an annular pitch stop element 28 held immovable axially between a flange 32 on an annular member 33 and a shoulder 34 on a sleeve member 35 secured, together with the annular member 33 to a second annulus 38 rigid with the propeller hub 10. Ratchet teeth 55 on the back of the master gear 20, which permit increase but not decrease of pitch, face co-operating teeth 54 on an axially movable annular pitch lock element 45 urged towards the master gear 20 by springs 49 but restrained from engagement therewith by hydraulic pressure applied to a servo-chamber 52 to act on a piston face 51 on the lock element 45 ; movement of the element 45 is further limited to the constant speed range of operation by lugs 56 on the element which in the #, feathering and reverse ranges encounter a flange 57 on the sleeve 25 but in the constant speed range can pass through gaps in the flange. The lock element 45 is held against rotation relatively to the hub 10 by straight axial splines 44 thereon engaging splines 46 on the annulus 38. The splines 44 also engage splines 43 on an axially movable low pitch stop element 39 provided with jaws 40 facing jaws 29 on the pitch stop element 28 and urged towards them by the springs 49 but opposed by hydraulic pressure in a servo-chamber 42 acting on a piston face 41 on the stop element 39 under manual control of a rotary valve 71, Fig. 2. During normal constant speed operation, pressure fluid from a line 63 flows along a passage 64 to the space between lands 94, 95 on a valve 93 in a chamber 69, through a passage 116 and line 117 to the servo-chamber 52 of the pitch lock element 45. If the propeller speed rises a predetermined amount: e.g. 5 per cent, a speed sensitive valve 107 overcomes the resistance of its spring 111 and moves a land 110 thereon above ports 102 in a valve sleeve 98 thus opening a passage 115 to drain and permitting a spring 96 beneath the valve 93 to raise it and open to drain the passage 116 and line 117 connected to the servo-chamber 52 of the pitch lock element 45. The springs 49 then engage the ratchets 54, 55 and prevent further decrease of pitch. Specifications 779,116 and 786,368 [Group XVII] are referred to.
